Rockers Bono and The Edge performed a surprise set on an underground train on the U2 subway line

U2 stars Bono and The Edge played a surprise set for commuters who boarded a subway line in Berlin, Germany Wednesday.

The subway line is also coincidentally called U2 subway.

The duo played an impromptu set for 120 lucky competition winners -- who applied for tickets for the underground train on the subway through a local radio station Radioeins.

The winners had boarded an underground train at Deutsche Oper to perform acoustically for 15 minutes.The set included "One" and new track "Get Out of Your Own Way" from their latest record, "Songs of Experience".
